Specification of Letters Patent. Patented June 22, 1915.

Application filed April 20, 1915. Serial N 0. 22,566.

V which the following is a specification.

This invention relates to certain new and useful improvements in ice creepers.

The primary object of the invention is the provision of a creeper that is easy and cheap to manufacture but which maybe readily clamped upon and removed from a shoe heel.

A further object is :to provide a creeper plate removably secured'to the tread portion of a shoe heel by binding cam operated clamping means, the same being readily re-- leasable but locked in position when operatively positioned.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists inthe novel combinationand arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings forming a part of this application and lnwhich' like designating characters refer to corresponding parts throughout the several views, Figurel is a side elevation of the device operatively positioned upon the heel of a shoe. Fig. 2 is a front elevational view of the device. Fig. 3 is a top plan view thereof. Fig. 4: is a central sectional viewttaken through the forward portion of the device and the locking means therefor, and Fig. 5 is a perspective view of the forward portion of the device with parts thereof removed.

Referring more in-detail to the drawings, a-shoe 10 is illustrated having the present invention operatively clamped upon the heel 11 thereof.

A tread plate 12 conforming substantially slightly greater length. The said arms have inwardly-extending serrated flanges 16 forming teeth for engaging the adjacent side of the shoe heel as best illustrated in Fig. 1.

The forward side'of the tread plate 12 has a cruciform frame 17 mounted thereon and provided with oppositely positioned straps 18 upon its opposite arms 19.

An encircling metallic strap 29 is centrally secured as at 2-21 to the inner side of the rear arm 15 and adjacent the upper end thereof,

faces 25 being spaced apart and positioned upon opposite sides'of a pivot pin 26.

An operating means is provided for con I ,ne cting the adjacent strap ends composed of a segment cam 27 centrally pivoted upon the said pin 26 and having opposite camslots 28 which sli'dably receive cam ains 29 therein which are mounted adjacent t 1e free ends of the said strap 20 and upon opposite sides of, the pin 26. The said segment cam 27 has an operating, arm 30 extending therefrom, and the same is adapted to slidingly engage a locking wedge 31 upon theouter side of the frame 17. lVith the arm 00 moved away froin the said wedge 31, the segment cam will be shifted for releasing the strap 20 by separating the ends 25 thereof and in this position, the crecpcrmay readily be'positioncd upon the heel with the strap surrounding the same and the teeth 16 arranged adjacent the side of the heel. morementof the handle 30 to its locked p0? sition in engagement with the wedge 31 will and the arms 14; and 15 being slightly resilient. the top toothed flanges thereof will be forcibly drawn into seating engagement with theshoe heel and the creeper will be thereby firmly looked upon the heel. The handle 30 will ride upwardly upon the wedge 31 and by itswedge action will be retained in engagement therewith in its locked operative position, while the handle may be readily swung out of engagement therewith for releasing the arm teeth and allowing the creeper to be removed from the heel.

\Vhile the iorm of the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that minor changes may be made without departing Q i mes es from the spirit scope of intention as-claimed.

' Whatl claim as new isz 1. A creeper comprising a late, upwardly projecting side and rear heel engagii arms mounted thereon, a

frame carried oy the forward portion of the 'saiiigqlate, apositioning strap centrally seem to the said'rear arm and slidably engaging said side arms and having its opposite ends inturned adjacent the said frame and connected thereto, and shiftable c1amp-' ing means connecting the ad aeent ends of the strap.
